选用部分形态、产量和生理指标,应用隶属函数法对26个主栽水稻品种进行了抗旱性综合评价,结果表明:在干旱胁迫条件下,各品种的单株产量、单株有效穗、结实率、穗长及叶片相对含水量、叶绿素含量显著下降;根据这些指标的平均隶属函数值,鉴定出了Y两优1号等7个抗旱性较强的品种和两优培九等3个对干旱敏感的品种。
Selection of some morphological, yield and physiological indicators, the application of membership function method of 26 major rice varieties were evaluated for drought resistance, the results showed that: under drought stress, the variety of single plant yield, effective panicle per plant, seed setting rate , Spike length and leaf relative water content, chlorophyll content decreased significantly. Based on the average membership function values of these indexes, seven drought-sensitive varieties such as Y Liangyou 1 and 7 drought-sensitive varieties such as Liangyoupeijiu were identified .
